一、前言 近年来本公司应国内外用户的要求,已经交付了36台300kW6565滚筒采煤机。但是国内外用户还需要机型小功率大的采煤机,为此研制了体积小功率大,结构紧奏的新型采煤机,以扩大产品市场。于85年9月开始研制,86年7月下旬研制成功,其结果报告如下。 二、研制的基本方针 该设备是在6565M型的基础上按以下设计方针研制的,它充分反映了三井三池制造厂长年的设计制造及实际工作成绩。 1.出煤率高 (1)为了提高出煤率而研制了400kW高功率电动机。考虑到替换方便,电源采用1000V。 (2)可快速切割。 (3)装有电力控制机构以发挥电机功率。 (4)采用无安全销式截割头。
I. Introduction In recent years, our company has delivered 36 sets of 300kW6565 roller shearer at the request of domestic and foreign users. However, users at home and abroad also need large shearer with small power. Therefore, a new type of coal shearer with small power and small structure has been developed to expand the product market. Development began in September 1985, and development succeeded in late July 1986. The results are reported as follows. Second, the development of the basic principles The equipment is based on the 6565M-based design guidelines developed by the following, which fully reflects the Mitsui Sanchi manufacturing plant for many years of design and manufacturing and the actual performance. 1. High rate of coal (1) In order to improve the rate of coal developed 400kW high-power motor. Taking into account the easy replacement, the power used 1000V. (2) can be cut quickly. (3) equipped with power control mechanism to play the motor power. (4) No safety pin cutting head.
